Description of problem:
"Iteration" was the old way to specify Version.
Since we now mention "Version" as Version, the word "Iteration" should be replaced to avoid confusion.

Version-Release number of selected component (if applicable):
zanata-python-client-1.3.1 and
commit ab314cee446132875151823aaf9807c18c564ac2
